Average Monthly Water Bill in the United States

With water costs climbing to eye-watering rates, it’s more important than ever to understand how your water bill is being calculated. When you’re hit with higher water charges, it's important to grasp the methodology used in determining your water bill to ensure you get what you pay for.

How is Water Bill Calculated in the United States?

The water bill in the United States is calculated by two factors mainly, including:

  • Water usage
  • Types of water pricing

Water Usage

Water usage refers to the amount of water consumed within a specific period, typically measured in gallons. In the United States, water bills are typically based on usage. However, the specific pricing model determines how the water bill is calculated.

Types of Water Pricing

In the United States, water utility companies offer mainly four types of water pricing, including:

  • Flat Rate Pricing
  • Metered Pricing
  • Increasing Block Rate Pricing
  • Decreasing Block Rate Pricing

Flat Rate Pricing

In a flat-rate pricing model, your water costs remain constant regardless of the volume of water used by the customer. Flat-rate water pricing accounts for an estimated 60% of all water bills in the United States.

In California, the average residential water bill is $76 per month, as of 2023. This rate is the same for all customers, regardless of their usage.

The primary challenge under a flat-rate model is promoting efficient water use. When there is no penalty for excessive water consumption, such as leaving the tap running unnecessarily, it becomes harder to encourage conservation efforts.

Metered Pricing

In metered pricing model, the customers are charged based on the actual amount of water they consume, as measured in units by a water meter. This means, higher water consumption results in higher bills.

For instance, in New York City, the average residential water bill is $1.5 per unit of water used. The first 150 units of water are free, and then the you'll be charged for each additional unit of water used.

Metered pricing encourages water conservation as customers are billed based on their actual water usage. It provides an incentive for individuals to be mindful of their water consumption and adopt water-saving practices.

However, water pricing can become more intricate than a simple flat rate or metered pricing. Water utility companies employ various pricing models to influence consumer behavior. One common approach is the use of increasing or decreasing block pricing, which accounts for an estimated 10% of all water bills in the United States.

Increasing Block Rate Pricing

In an increasing block rate structure, the cost of water rises as your usage increases. For instance, a water utility company might charge $1 per unit for the first hundred units consumed, $1.5 per unit for the next 100 units of water used, and $2 per unit for any additional water used.

In the city of El Paso, Texas, water utility companies charge $1.25 per unit of water for the first 200 units of water used, $1.5 per unit for the next 200 units of water used, and $2 per unit for any additional water used.

Increasing block rates are commonly employed in areas where water scarcity is a concern, particularly in urban areas. The intention behind this pricing strategy is to discourage excessive water consumption and promote responsible usage. If you find yourself on increasing block plan, it's essential to carefully consider your water consumption choices, as the cost can escalate with higher usage.

Decreasing Block Rate Pricing

In contrast to increasing block rates, a decreasing block rate structure charges less per unit of water as consumption levels rise. For example, a water utility might charge $2 per unit of water for the first 100 units of water used, $1.5 per unit for the next 100 units of water used, and $1 per unit for any additional water used, such as one thousand gallons.

In the city of Phoenix, Arizona, water utility companies charge $2 per unit of water for the first 100 units of water used, $1.75 per unit for the next 100 units of water used, and $1.5 per unit for any additional water used.

While less common in urban areas, decreasing block rates are frequently implemented in rural areas where agricultural practices require significant water usage.

Although counterintuitive for city dwellers, decreasing block pricing mechanism allows water utility companies in areas with abundant water resources to maintain profitability while accommodating customers with higher water needs. By reducing the cost per gallon as consumption increases, it ensures that individuals or businesses requiring larger quantities of water are not heavily penalized.

How to Reduce Your Water Bill

Follow are the top three ways to reduce your water bill:

  • Shorten your showers: A typical shower uses about 2 gallons of water per minute. By shortening a 10-minute shower by just 2 minutes, you can save about 8 gallons of water.
  • Fix leaky faucets and showerheads: A leaky faucet can waste about 5 gallons of water per day. By fixing a leaky faucet, you can save about 150 gallons of water per month. Additionally, addressing a showerhead with ten drips per minute can result in conserving over 500 gallons of water in a year.
  • Upgrading your appliances: Upgrading to newer, water-efficient appliances have the potential to decrease water consumption by 20%, as per U.S. Environmental Protection Agency. For instance, a high-efficiency toilet using 1.28 gallons per flush compared to 3.5 gallons per flush in older models can save about 2,200 gallons of water per year. Additionally, look for the WaterSense logo when shopping for water-based appliances such as water filter systems, washing machines, and dishwashers as it signifies water-efficient options promoted by the EPA's WaterSense partnership scheme.
